Programs compiled/linked with -mno-cygwin are *not* Cygwin apps, and the
memory management in that case is provided by Microsoft's runtime library
(CRTDLL in this particular case).

Other than perhaps a few odd embedded systems, pretty much everything else 
in the world uses runtime libraries.

The linker typically has nothing to do with memory management.

Cygwin/Mingw programs use malloc or some package built on top of it, 
and malloc uses OS-specific hooks to allocate chunks of memory and
manages that on behalf of the user. Doug Lea's excellent paper on
his malloc package talks about this issue, and so do plenty of other
articles and books.

I get the feeling that I haven't a clue as to what information you're 
really after.
